财产保险火灾风险评价方法与标准制定的研究

财产保险火灾风险评价方法及其标准的制定在我国处于空白状态。根据安全系统工程学的思想，提出了基于财产保险的建筑火灾风险评价指标体系的建立方法，利用层次分析方法确定各指标的权重，并根据科学性和操作性的原则对指标的评价尺度进行了划分；在此基础上得出了建筑火灾风险综合分值评分表和核保和费率浮动方法。结果表明:利用层次分析方法确定各指标权重的方法是比较科学的，权重分布比较符合实际情况。结果显示:基于安全系统工程学思想的方法，可以为火灾保险国家标准的制定提供帮助。     

关于价格指数缩减法计算工业发展速度的研究

 建国以来，我国一直沿用不变价格工业法计算工业发展速度，这种方法在国家定价占绝对主导地位的计划经济时代发挥了一定的作用。随着我国市场经济体制的建立，不变价法的弊病越来越大，亟待采用适合市场经济特点的新方法。目前，国家统计局正在对两种新方法——生产指数法和价格指数缩减法进行对比计算，从试算结果看，价格指数缩减法优势较为明显。

An individual-based model for competingDrosophila populations

An individual-based model forDrosophila is formulated, based on competition amongst larvae consuming the same batch of food. The predictions of the model are supported by data for single speciesDrosophila populations reared in the laboratory. The model is used to build a simple discrete model for the dynamics ofDrosophila populations that are kept over a number of generations. The dynamics of a single species is shown to give either a stable equilibrium or fluctuations which can be periodic or chaotic. When the dynamics of a species in the absence of the other is periodic or chaotic, we found coexistence or two alternative states, on neither of which the species can coexist.     

中国干群矛盾的类别、发展趋势及缓解机制研究

干群矛盾是中国社会矛盾中最特别、最具有爆炸性的类型,全面解析干群矛盾是社会矛盾预警及治理的重要环节.文章从性质、主体、地域、表现形式、发展阶段、激烈程度等方面对干群矛盾进行分类,把握其发展的现状,概括出具有普遍性、局部激化、振荡调整、危害性大等特征,指出主要诱因包括政治利益冲突、经济利益冲突和情感利益冲突.预测其发展趋势将更为激烈.而且成为其他社会矛盾演化成大规模冲突的催化剂.提出了"一个中心三个层面"、预警机制、综合控制机制等缓解、化解干群矛盾的机制.

Double Sampling Ratio-product Estimator of a Finite Population Mean in Sample Surveys

It is well known that two-phase (or double) sampling is of significant use in practice when the population parameter(s) (say, population mean X¯) of the auxiliary variate x is not known. Keeping this in view, we have suggested a class of ratio-product estimators in two-phase sampling with its properties. The asymptotically optimum estimators (AOEs) in the class are identified in two different cases with their variances. Conditions for the proposed estimator to be more efficient than the two-phase sampling ratio, product and mean per unit estimator are investigated. Comparison with single phase sampling is also discussed. An empirical study is carried out to demonstrate the efficiency of the suggested estimator over conventional estimators.     

Minimizing makespan in an ordered flow shop with?machine-dependent processing times

We consider a generalization of the proportionate flow shop problem with the makespan objective. Each job has a processing requirement and each machine has a characteristic value. In our case, we assume that the time a job occupies a machine is equal to the processing requirement of the job plus a setup time that is equal to the characteristic value of that machine. In this paper, we consider permutation schedules and show that the problem is solvable in polynomial time when the number of machines is fixed.     

A Translation and Validation Study of the Life Orientation Test Revised in the Greek Speaking Population of Nurses among Three Hospitals in Athens and Ioannina

The life orientation test-revised (LOT-R) (Scheier et al. in Journal of Personality and Social Psychology 67:1063–1078, 1994) is a brief measure for assessing dispositional optimism. The aim of this study was to develop a Greek language version of the LOT-R and to assess the instrument’s psychometric properties. The LOT-R was translated and culturally adopted in Greek language, and the final version was administered, along with a questionnaire consisting socioeconomic characteristics and a single item measuring optimism, to 276 Greek speaking, hospital nurses (222 female, 54 male), aged 22–65 years (mean 37.8, SD 8.3). Results showed that the LOT-R has good internal consistency (Cronbach’s α = .71 and item total correlation coefficients from .27 to .73, a unitary structure, and stability over a 3-months period (r = .66). Moreover, the Greek version of the scale exhibited good convergent validity with single-item optimism scale (r = .73). Principal components analysis revealed a two-factor structure representing the constructs of optimism and pessimism. The Greek life orientation test revised appears to be a valid tool in assessing dispositional optimism in Greek speaking people and is expected to facilitate the examination of optimism in Greek speaking populations.
